MCP1652ST-E/MS Equivalent & Substitute Parts

Part Overview

The MCP1652ST-E/MS is a DC-DC controller IC from Microchip Technology designed for boost, flyback, and SEPIC regulator topologies with positive output configuration. This active product operates as a transistor driver for step-up and step-up/step-down applications. The device is packaged in 8-MSOP surface mount format with tape and reel packaging. Finding equivalent and substitute parts is necessary when tape and reel packaging is unavailable, when alternative moisture sensitivity levels are required, or when different packaging formats better suit procurement and assembly requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MCP1652ST-E/MS is determined by strict equivalence across the following parameters: manufacturer (Microchip Technology), base product number (MCP1652 or MCP1650 series), package type (8-MSOP), electrical specifications (2.7V ~ 5.5V supply, 750kHz switching frequency, 80% maximum duty cycle), topology support (Boost, Flyback, SEPIC), output configuration (positive), and operating temperature range (-40°C ~ 125°C). Packaging format (tape and reel, tube, or cut tape) and moisture sensitivity level (MSL) are secondary parameters that define substitute relationships without affecting functional compatibility. All substitute parts maintain identical control features (current limit, enable, low battery, power good) and regulatory compliance (ROHS3, REACH unaffected, EAR99).

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products from Microchip Technology with ROHS3 compliance and REACH unaffected status. Selection between MCP1652ST-E/MS, MCP1652S-E/MS, and MCP1650RT-E/MS depends on packaging format requirements and moisture sensitivity constraints. The MCP1652ST-E/MS in tape and reel format with MSL 1 is suitable for high-volume automated assembly with unlimited shelf life. The MCP1652S-E/MS in tube packaging with MSL 2 accommodates manual assembly workflows with one-year moisture sensitivity storage limits. The MCP1650RT-E/MS in cut tape and Digi-Reel format with MSL 1 provides flexibility for mixed-volume production with unlimited shelf life. All parts maintain identical electrical performance and topology support across boost, flyback, and SEPIC configurations.

Frequently Asked Questions (FAQ)

Q: Can MCP1652S-E/MS replace MCP1652ST-E/MS in production? A: Yes. Both parts share identical electrical specifications, topology support, and package dimensions. The difference is packaging format (tube versus tape and reel) and moisture sensitivity level (MSL 2 versus MSL 1). Verify that your assembly process accommodates tube packaging and that the one-year MSL storage requirement aligns with your supply chain timeline.

Q: What is the difference between MCP1652 and MCP1650 series? A: The MCP1650RT-E/MS uses the MCP1650 base product number while MCP1652ST-E/MS and MCP1652S-E/MS use the MCP1652 base product number. All three parts maintain identical electrical performance, switching frequency, duty cycle, and operating temperature specifications. The base product number difference reflects manufacturing lineage but does not affect functional compatibility.

Q: Does packaging format affect electrical performance? A: No. Tape and reel, tube, and cut tape packaging formats are mechanical delivery methods only. Electrical specifications, switching characteristics, and control features remain identical across all three parts.

Q: What does MSL 1 versus MSL 2 mean for component storage? A: MSL 1 (Unlimited) allows indefinite storage under controlled conditions without moisture bake-out requirements. MSL 2 (1 Year) requires moisture bake-out if the component is stored for more than one year or exposed to high humidity environments. Select MSL 1 parts for long-term inventory or MSL 2 parts for just-in-time procurement workflows.

Q: Are all three parts suitable for boost, flyback, and SEPIC topologies? A: Yes. All three parts support identical topology configurations: boost, flyback, and SEPIC regulators with positive output step-up and step-up/step-down functionality.
